I've got a few qustions I've been working on for the past week. If these questions have already been answered, forgive me, I don't have my own computer, and the library only allows me an hour a day, also I'm real short on cash and can't afford to pay for information right now. If you have a link to a place online with answers to any of the following please supply them. Please & thank you.
1) The proper proportions to mix ammonium and chlorine to make ammonium chloride for the purpose of precipitating platinum out of an aqua regia solution. If I want to precipitate 1 ounce of platinum how much ammonium chloride do I need for that?
2) If I buy muretic acid at he hardware store in solid crystall form, what is the process for getting that into a liquid form of the acid, to be mixed with Nitric Acid to make Aqua Regia. I'm guessing I mix the crystalls with water, but how do I judge the concentration, and what concentration do I need.
3) How/Where can I go online to learn how to make concentrated nitric acid (%70)?
4) About how much platinum is in your average spent catalyst (normal sized vehicle), most people are telling me around 1 ounce. please advise.
